Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an external UPS and backup power system are added separately to provide backup power function, then the backup power function is achieved, but the occupied space and system cost increase
Solution Approach 1:
The patent integrates the backup power function into the frequency converter by adding a battery pack and DC-DC conversion module within the same cabinet. This merging of functions eliminates the need for a separate external UPS system, reducing occupied space while maintaining backup power capability for the liquid-cooled circulating pump
Solution Approach 2:
The frequency converter is designed to perform multiple functions: both driving control of the liquid-cooled circulating pump and backup power supply. By making the frequency converter universal, the system eliminates redundant components and reduces overall system complexity and space occupation
2Reliability
If an external UPS and backup power system are added separately to provide backup power function, then the backup power function is achieved, but the system cost increases
Solution Approach 1:
The patent combines the backup power function with the frequency converter, eliminating the need for a separate external UPS system. This integration reduces system cost by removing redundant components and reducing the overall bill of materials while maintaining the required backup power functionality
3Reliability
If the frequency converter and backup power system are independent, then the backup power function is achieved, but the system efficiency decreases due to repeated functions
Solution Approach 1:
The frequency converter is designed to serve dual purposes: driving control and backup power supply. This eliminates repeated functions and reduces energy loss by avoiding redundant power conversion stages. The integrated design ensures that the same hardware components perform multiple functions efficiently
